The quality of Chinese medicinal materials depends on the content of bioactive components, which are affected by the environmental factors of different planting regions. In this research, integrated analysis of the transcriptome and metabolome of 'Chachi' was performed in two regions, and three orchards were included in the analysis. In total, only 192 compounds were found in fresh peels, and among 18 differentially accumulated flavonoid metabolites, 15 flavonoids were enriched in peels from the Xinhui planting region. In total, 1228 genes were up-regulated in peels from Xinhui, including the and genes, which are involved in the salt stress response. Overall, based on the correlation analysis of flavonoid content and gene expression in peels of 'Chachi', we concluded that the authenticity of the GCRP from Xinhui may be closely related to the higher content of naringin and narirutin, and the increase in the content of these may be due to the highly saline environment of the Xinhui region.
中药材的质量取决于其生物活性成分的含量，而这些成分又受到不同种植区环境因素的影响。在这项研究中，对‘茶枝柑’的转录组和代谢组进行了综合分析，分析中包含了两个地区的三个果园。结果仅在新鲜果皮中发现了 192 种化合物，在 18 种差异积累的类黄酮代谢物中，有 15 种类黄酮在新会种植区的果皮中富集。在新会的果皮中，共有 1228 个基因上调，其中包括 和 基因，这些基因参与了盐胁迫反应。总的来说，基于果皮中类黄酮含量和基因表达的相关性分析，我们得出结论，来自新会的 GCRP 的真实性可能与较高的柚皮苷和新橙皮苷含量密切相关，而这些含量的增加可能是由于新会地区的高盐环境所致。
